Embodiment 1

[0026] The preparation method of the bacterial cellulose-based power generation fiber of the present embodiment comprises the following steps:

[0027] (1) Place the bleached bacterial cellulose wet film between a pair of holding rollers and feed it at a speed of 10 mm to 100 m / min; the diameter of the holding rollers used is 20 to 3000 mm.

[0028] (2) The cellulose film output from between the rollers is punctured, split and combed at a high speed by needle-punching on the surface of the licker-in roller, and the bacterial cellulose wet film is transformed into bacterial cellulose fibers; the bacterial cellulose fibers are filtered through a filter press treatment to prepare bacterial cellulose superfine fiber strips; the moisture content of the bacterial cellulose superfiber after pressure filtration is between 15% and 50000%, the diameter of the superfine fiber is 10-500nm, and the length of the superfine fiber is 200nm ~200mm between.

Abstract

A method for preparing bacterial cellulose-based power generation fibers, which comprises immersing bacterial cellulose superfine fiber strips in nano-ZnO sol to obtain bacterial cellulose B, which is taken out for use; the bacterial cellulose B is put into an amino zinc salt solution, reacted After a period of time, bacterial cellulose C is formed; the bacterial cellulose C is subjected to conductive treatment such as ITO and AZO; bacterial cellulose fibers with power generation properties are prepared. The finished product made by the method of the invention is the bacterial cellulose-based power generation fiber and yarn, which can be further processed through the existing weaving and weaving technology. The formation of mechanical power generation components of different scales is widely used in fields such as environmental monitoring, implantation of biochips in the body, automobiles, construction, military, etc., which have different size and power requirements for self-generating components.

Description

technical field [0001] The invention relates to a preparation method of bacterial cellulose-based power-generating fibers and yarns, in particular to a preparation method of bacterial cellulose-based power-generating fibers and yarns that can be applied to self-generating power sources of miniature and high-performance electronic devices and sensors. Background technique [0002] With the development of economy and society, electricity has become an indispensable part of society. The current situation of electricity in our country is lack of electricity in cities, remote areas without electricity, valleys in spring and autumn, and peaks in winter and summer. Although the country has started the west-to-east power transmission project, the power loss of long-distance power transmission and the high cost of laying lines have made the cost of power rise instead of falling. According to data released by the China Electricity Council, my country's electricity consumption reached...
